The SG-Ⅲ laser facility has successfully demonstrated its capability to deliver 60 TW/180 kJ ultraviolet laser (351 nm) onto the target, which establishes it the worlds second and Asias largest laser driver for inertial confinement fusion (ICF) research. On one hand, the construction of the SG-Ⅲ laser facility systematically advances and maturates a series of core capabilities of domestic high power laser field, such as integrated design, integrated installing, fine assembling and calibration, manufacture, optics diagnostics, key technologies, and so on. On the other hand, it represents that we have already developed an optical engineering system for future larger ICF laser driver research and construction.
